Example Embodiment

[0023] The technical scheme of the present invention will be further explained below in conjunction with the drawings.

[0024] See Figure 1-3 As shown, the above-mentioned flexible manipulator includes a connecting column with a hollow cavity 1, a total air inlet 122 on the connecting column 1 and communicating with the hollow cavity, a connecting plate 3 arranged at one end of the connecting column 1, at least Two groups of finger mechanisms. In this embodiment, there are four sets of finger mechanisms. The four sets of finger mechanisms are ringed on the outside of the connecting column 1 evenly spaced. The surrounding centers of the four sets of finger mechanisms are located on the axis of the connecting column 1. The angle between two of the four groups of finger mechanisms is 90°.

[0025] The finger mechanism includes a finger finger surface 4, a finger back 5 connected to one side of the finger finger surface 4, the finger finger surface 4 is distributed in a plane, the ...

Abstract

The invention discloses a flexible mechanical hand which comprises a connection column with a hollow cavity, a total air inlet formed in the connection column, a connection plate arranged at one end of the connection column and at least two finger mechanisms. Each finger mechanism comprise a finger face, a finger back, a first cavity arranged between the finger face and the finger back, at least one semicircular arch body arranged on the finger back, a second cavity formed in the semicircular arch body and communicating with the first cavity, and a convex portion which is convexly arranged onthe other side of the finger face and provided with the lower surface being an inclined face, wherein the swelling deformation of the finger back is larger than that of the finger face. Each finger mechanism further comprises a connecting piece connected to the root of the corresponding finger, a third cavity arranged in the connecting piece and communicating with the first cavity, an air inlet formed in the connecting piece, an air outlet formed in the connection column and communicating with the air inlet, a sliding groove formed in the connecting piece, and a sliding rail arranged on the connecting plate and used for penetrating into the sliding groove. The flexible mechanical hand is large in grabbing force and capable of gabbing objects with different sizes.

Description

technical field [0001] The invention relates to a flexible manipulator. Background technique [0002] In the field of industrial automation, mechanical claws for grabbing objects in cooperation with mechanical arms are widely used. Due to the large grasping force of rigid fingers, most robotic grippers are composed of rigid fingers. However, rigid fingers are difficult to achieve lossless grasping of soft objects, and flexible fingers are required to achieve it. And flexible finger, the frictional force of its contact surface with article is less, in the process of clamping, often the phenomenon that article falls off takes place. [0003] Due to the different specifications and sizes of items, it is necessary to use mechanical claws of different specifications for grasping, and the cost is high. Contents of the invention [0004] The purpose of the present invention is to provide a flexible manipulator, which can greatly increase the friction force when grabbing items,...
